I've got a weird problem with my PB 667 DVI that I was hoping you all might be able to help with. Sometimes, it just won't start up. And it takes a lot of jimmy-rigging to get it to start up -- and even then it often crashes on the happy Mac screen, during the startup process, etc. I try stuff like resetting the PRAM and the PMU, letting it sit for a while, etc. I've tried taking out the memory modules and replacing them as well. That doesn't seem to be the issue. I've also formatted the hard drive (zeroing all sectors) and just installed OS 9 and/or OS X...still crashes sometimes... I've tried resetting the Open Firmware as well (using "reset-nvram" and "reset-all"). The Hardware Test CD doesn't ever turn up anything. Sometimes it has crashed while running the tests. But I've had the PowerBook running the test CD in loop mode for over a day now, and after 220 cycles of testing, it hasn't detected a "failure" yet. Sometimes on startup, I'll get 3 or 4 "beeps." Then the sleep light will blink 3 times (faster than usual), then a fourth time (on for about a second), and the cycle of lights will continue until I unplug the AC adapter and battery. And then sometimes it starts, sometimes it doesn't. If anyone has any ideas, I'd love to hear them! Thanks!
